TLDR
Guppies were exposed to a complex mixture of polychlorinated dibenzo-p -dioxins (PCDDs) and polychlorined dibenzofurans (PCDFs) in the presence and absence of sediment for 21 days as mentioned in this paper.About:

Fish bioaccumulation and biomarkers in environmental risk assessment: a review
TL;DR: There is little doubt that measurements of bioaccumulation and biomarker responses in fish from contaminated sites offer great promises for providing information that can contribute to environmental monitoring programs designed for various aspects of ERA.

TL;DR: In this paper, the authors investigated the long-term fate of organic matter in the geosphere and its role in sedimentary organic matter preservation and degradation in the geological timescale.

Biomonitoring aquatic pollution with feral eel (Anguilla anguilla): I. Bioaccumulation: biota-sediment ratios of PCBs, OCPs, PCDDs and PCDFs.
TL;DR: In this article, the authors investigated the bioaccumulation of persistent organic trace pollutants in eels, considering partitioning, uptake from contaminated water (bioconcentration) and food (biomagnification), clearance, and bioavailability.

Bioaccumulation of polychlorinated dibenzo-p-dioxins in sediment by oligochaetes: Influence of exposure pathway and contact time
TL;DR: Based on comparison of predicted accumulation from pore water and observed accumulation by sediment-exposed oligochaetes, it was concluded that 1.4-fold greater accumulation occurred due to assimilation of TCDD and OCDD from ingested sediment.

Fish predation by semi-aquatic spiders: a global pattern.
TL;DR: It is provided that fish predation by semi-aquatic spiders is geographically widespread, occurring on all continents except Antarctica, and that fish prey might be an occasional prey item of substantial nutritional importance.

Physical-chemical properties of chlorinated dibenzo-p-dioxins
TL;DR: In this paper, the authors derived correlation equations for these properties as a function of chlorine number and molar volume, which enabled the solubility and octanol-water partition coefficients of most congeners to be estimated with an accuracy within a factor of 2 and vapor pressure and Henry's law constant within a fador of 5.

A novel method for measuring membrane‐water partition coefficients of hydrophobic organic chemicals: Comparison with 1‐octanol‐water partitioning
TL;DR: The results indicate that n-hexane and 1-octanol are satisfactory surrogates for DMPC membranes for chemicals with 1- octanol-water partition coefficients (log KOW) less than 5.5 or molar volumes less than 230 cm3/mol.
